Visual Studio 2022 is Auto-collapsing Solution Explorer Folder Trees

I've upgraded from VS 2019 to VS 2022. I have found that Visual Studio 2022 is automatically collapsing Solution Explorer sub-folders trees whilst I edit the code. I do not have the CodeMaid extension installed and I have ticked the checkbox "Track Active Items in Solution Explorer" in Tools->Projects and Solutions->General.
Any ideas as to what I should do to keep these sub-folder trees expanded as I would like them to be?

I cannot find an Open File Dialog a Visual Studio 2022 WPF project

In previous editions of Visual Studio I could get an OpenFileDialog by creating a reference to System.Windows.Forms. In Visual Studio 2022, when I click on Add and choose Reference, I can't find a reference to System.Windows.Forms. What is going on?

How to reference OneNote interop from Visual Studion 2010

I am trying to use the OneNote interop from visual studio 2010. I have OneNote 2010 installed, I am building a .net 2.0 win forms app. I add a reference, Select the COM tab, and choose either Microsoft OneNote 12.0 Object Library or Microsoft OneNote 14.0 Object Library. Regardless of what I choose, when I click ok my references list in my project shows Microsoft.Office.Interop.OneNote with a yellow warning icon next to it. If I try to compile I get an error:
The input file 'C:\Program Files\Microsoft Office\Office14\ONENOTE.EXE' is not a valid type library. D:\Develop\2.0\Projects\Office\OneNote\File Import\OneNote File Import\TlbImp OneNote File Import
I've done this before in earlier version of Visual Studio, is there something else I need to do?
No. I just tried and it works fine for me. Have you tried a project from scratch? Does it work if you target 4.0?
